Brother 4100 Scanning/Printing Problem

Hi to all - I just picked up a used 4100 that I was told had been in service for one year and was in working condition prior to it's removal from service. The unit powers on and goes through a clearing cycle and warm- up period. I can access menu items for setup functions. The unit does not scan items for faxing or copying and it will not print. Originals are recognized when placed into the ADF and cleared when left there during a startup routine. I have tried to print a report 1 to determine print function status and nothing happens other than printing showing on screen. I hear a slow cadence clicking sound that starts and stops. Machine eventually goes into sleep mode. I have tried a system clear. I tried a system clear. I get to parameter init keying in 91 in maintence mode but cannot escape out using 99. The seller agreed to accept $25 for the machine (has extra tray) so I have some wiggle room to invest in parts.& an repair manual download for diagrams. All suggestions regarding possible fix and a good place to get the suggested parts needed will be appreciated. - Bob Sr.

    Thanks for that link - I have the user manual - I am going to purchase a repair manual (if I get feedback that it is worth repairing) so I have access to information on replacing the suspected bad partt and for general maintenance. I see a few listed for download purchases doig a google search. Any recommendations relative to a good choice in this area would alsovbe appreciated. I was just laid off and am looking to set up a home office so I am trying to get some decent equipment as resonable as possible. This machine has high ratings so those are thevreasons I am looking into repairing this myself. Thanks again.

    My customers called me and said that my faxes were terrible. Every page has vertical lines blackened three quarter page. It happens to all the copies I made, too. Received copies are just fine.

    Anyone if the scanning light or glass is the problem?

    Can it be fixed? and where?

Right hand side of page has 1-1/2 inch horizontal streaks down the side

The scanning bar has 28 leds on it and on my 4100 the 6 leds on the right side were flashing on and off,it could be abad connection on that part of the scanning bar caused by a jamed paper.
to tell if your machine is a printing problem or a scanning problem print out the help menu {press the reports key then the 1 key} if it prints clear then every thing with the print cartrige is ok and the problem is in the scanning part of the machine.

On my Brother 4100 Fax machine, there is an absence of reproduction from top to bottom in the middle on copies only. Printing from the computer is okay.

Replace the copy element inside will shore this up the element is the OCR sensor once that is replaced things should be as normal and brother would carry the part. Otherwise there is not much else that can be done in this case, Thanks for using please od leave postive feedback for your free solution today.

4100 when I copy I get a black line down the middle Ok after cleaning inside top cover, but,comes back after a few copies. Printing and sending fax ok.

Try printing out a report. If the line is still there you need to use the wire cleaner on your print cartridge or if that doesn't work, replace the drum unit.
